I use a Canopus AVDC-100 device to capture VHS tapes on computer. The VHS camcorder that I use for playing the tapes back has just a mono audio, therefore I connect the camera’s single audio cable into one of the two audio channels of the Canopus unit and leave the other one unplugged. The Canopus unit connects into the computer via Firewire.
The properties of the captured video are 29.97 fps, DV Type 1, 24 bits, 720 x 480, 4:3, DV Audio – NTSC, 32 kHz 12 bit stereo. I do my editing using VS X2. Due to the mono sound I duplicate one of the audio channels to another. After editing the video I author a DVD using the following settings: 24 bits, 720 x 480, 29.97 fps, LFF, 8000 kbps, LPCM Audio, 48 kHz Stereo. The DVD will play just fine on the computer that I used for burning it and on my cheap 3-year-old Philips player. The trouble starts when I try to play it back anywhere else: It does play on my 10-year-old Toshiba DVD player but the audio volume is so low that you have to turn the volume on TV all the way up. It doesn’t play at all on my two other computers.
The above process works fine when I author DVDs from HV-20 DV footage. The discs play in all above mentioned equipment and the audio works fine too. I have even tried mixing footage from HV-20 and Canopus and when I play the disk back in my Toshiba the audio is okay with the HV-20 footage but with Canopus footage it is extremely low. I’m out of ideas so any tips or tribal knowledge will be greatly appreciated.
